Remember that one time Mickey Mouse made a cameo appearance in "The Empire Strikes Back"? During the epic fight between Luke and Vader? Right before Vader reveals his true identity to Luke? You don't? Here, let us show you.

The tip about the Disney character's secret cameo came from Pablo Hidalgo over at the "Star Wars" Blog, who appropriately described the image as "something that you’ll now never be able to un-see." How right he is.

The cameo comes right before Vader sends Luke flying out the window at Cloud City during their climactic battle. Hidden along the back wall, you can find a subtle outline of the iconic face and ears. While we don't know the origin story behind the reference, but let's just assume it was a message from the future.
